Not exactly sure how they decided the cut-off points (there are 3 "best" combos listed, but 6 "worst"), but they seem to be ranking by fWAR. Scoockie Genneeks is at 2.1 which would be just behind Chreth Sminorfia at 2.2. Markyle Reynoverbay is only at 0.8 due to Overbay's negative contribution.

Wow, yeah, he dominates that list. One of the more ironic names in baseball. At least he's not King.

I was a little surprised to see Rico Brogna up there. I thought he had a reputation as a good fielder. (But I see his seasonal dWARs are consistently negative.) Mark Grace, too -- four-time Gold Glove winner but he has a season over (under) -2 dWAR. Whoa! J.T. Snow too?

2. Are there some built-in problems with dWAR's evaluations at 1B? Most of the guys on bobm's list are famous for being awful. But a few of them are not. I suppose it could just be an off-year here and there.

So, J.T. Snow's -2 dWAR season was 1995, the year he won the first of 6 consecutive Gold Gloves. In every single one of those years he had a negative dWAR.

It's nearly impossible for a first baseman to post a positive dWar. You have to look are rField to rate a player. dWar is about one of the most useless stats you will ever see. (for the record, Keith Hernandez was .6 dWar over his career, but was 117 rField over his career.)

Having said that, JT Snow gold glove years rField was
-13
-2
-4
2
2
-4
so it was probably overrated.

When comparing players at the same position, dWAR and Rfield are essentially identical. The only difference is variation in the positional adjustments across eras. For the expansion era, these tend to be pretty small. In the early-mid 70s, George Scott got whacked to the tune of 8-9 runs per seasoon; in the early-mid 90s, Palmeiro got whacked at -9; in the 2010s, Fielder gets whacked at -10.

When comparing players across positions, you have to incorporate positional differences.
